Practical example of the Supervised Vicarious Calibration (SVC) method - ValCalHyp Airborne Hyperspectral Campaign

A novel reflectance-based approach for radiometric calibration and atmospheric correction of airborne hyperspectral (HRS) data, supervised vicarious calibration (SVC), was proposed by Brook and Ben-Dor in 2010. The present study aimed to validate the SVC method using simultaneously operated several different airborne HRS sensors that acquired data above several selected sites. The general goal of this study is thus to apply a cross-calibration approach to examine the capability and stability of the SVC method. The main assumption of
the SVC method is that radiometric and spectral performances and stability of all HRS sensors are varying in time and space, therefore the periodical calibration information, such as laboratory calibration, might not be correct or suitable for a particular campaign. Therefore, a method to assess the overall accuracy of at-sensor radiance response and its stability alongside with correcting the possible radiance drifts are crucial, and suggested by the CVS method.
